“…Orthokeratinization is not normally seen in the human oral mucosa, unless it is induced by irritation such as frictional stimuli , suggesting that this process provides extra protection. Moreover, the dorsal surface of the rat tongue mucosa is usually covered by thicker and denser orthokeratin than the ventral surface . This may provide an explanation why, in the present study, the dorsal surface appeared to be more resistant to change than the ventral surface.…”

In the epidermis from 4 cases of X-linked ichthyosis, granular cells contained a large number of keratohyalin granules of irregular surface, the largest ones having a spongy appearance. Keratinosomes were normal both in number and degree of extrusion. Corneal cells were linked by desmosomal discs up to the most superficial layers. The abnormal persistence of desmosomal discs may be a consequence of a decrease in the activity of acid hydrolases within the keratinosomes. In corneal cells there were a great number of melanosomes with normal appearance which may be responsible for scale pigmentation. Such increased number may be attributed to a deficiency in melanosome spontaneous degradation, rather than to an increased formation.

In the nasopharynx of the SMA mouse, the ‘intermediate epithelium’ occupies the transitional zone between the ciliated columnar and the stratified squamous epithelia. The intermediate epithelium showed gradations ranging from ciliated stratified low-columnar through stratified cuboidal to stratified squamous type. It is suggested that the intermediate epithelium shows the various stages of the epithelium transforming from the ciliated columnar to the stratified squamous epithelium, and that the basal cells ofthe ciliated columnar epithelium serve as the germinal layer for the transformation. The intermediate epithelium containing a few keratohyalin granules and many membrane-coating granules represented earlier stages of keratinization. The width of the microprojections in the stratified squamous epithelium was about doubled compared to that in the intermediate epithelium. It is suggested that the difference in width is caused by cell membrane distortion associated with keratinization and is regarded as an important marker of the start of keratinization.
